Bought my C43 estate back in December 2019-after a couple of months notice a whining between 50-80mph-was diagnosed as needing a new rear diff/replaced in March. Now the whining noise is back but currently in Germany so it’s the first big run at speed since then. Symptoms are that it starts at 50, most noticeable at 85, and only does it under acceleration. Take you foot off the pedal and it goes. Also notice some vibration up through the steering wheel at around 110, but not sure if connected or the wheels need balancing. Wheel set up is 19” with Michelin PS4 all round.
Car has MB used warranty to Dec21 and REALLY want this fixed/gone.
